4 Claims. 1 The present invention relates to a composition for use inmetal working, and more particularly I has reference to a compositionwhich will prevent loading of the cutting or grinding tool, therebymaterially increasing the cutting or grinding action and at the sametime the life of the tool, the composition additionally beingellicacious for lubricant purposes in metal spinning, extrusion dies anddeep draw dies.

There are, of course, numerous compounds which have heretofore beenproposed for facilitating cutting, abrading and similar operations, aswell as compounds which will function as a lubricant for various movingparts of machinery. However, it is felt that the composition 'of theinstant invention possesses important advantages over those currentlyemployed, in that it possesses a relatively wide range, insofar ascutting and abrading methods are concerned, as well as its employmentfor lubricating operations.

An important object of the present invention is to provide a compositionin solid form which, when applied to an abrading or grinding surface,becomes a highly viscous fluid in the inner granular areas of theabrading surface, thereby tending to function as a flotation medium for'the particles of the grinding agent loosened or dislodged in theabrading process.

A further object of my invention is to provide a composition of thecharacter set forth which will resist the peripheral speed of a wheel orother rotating body and thus not be thrown off, and also which resistsbreaking down temperatures caused by friction.

And still another object of the invention is to provide a compositionfor accomplishing the ends hereinabove set forth, wherein a controlagent is included for determining the melting point desired for theparticular operation being performed.

For a further understanding of the invention and of the objects andefficacy thereof, reference will be made to the following descriptionand to the annexed claims in which the novelty of the invention is moreparticularly set forth.

Viewing the invention broadly, it comprises tallow, paraffin, beeswax,citric acid, oxalic acid, urea, potassium citrate, and a suitablecoloring agent mixed in the proper proportions and sequence, the finalproduct preferably being cast or otherwise processed to provide a solidbody.

The major proportion of the end product is composed of tallow. paraflinand beeswax, and by virtue of the many factors which must be consideredin connection with various metal working operations, it is necessarythat a control for the melting point desired be present. For example, inspinning steel, a higher temperature is attained than is the case in thespinning of aluminum, and hence a higher melting point of the product isrequired to reduce the amount of throw off. Additionally, if thecomposition is employed on a grinding or abrading wheel, the compoundrequires a higher melting point in the case of a coarse abrading surfacethan is true of a fine abrading surface.

Another factor to be considered is the variance in the melting point oftallow, paraffin and beeswax. The melting point of tallow is between 45and 0., whereas paraffin melts between 45 and C. Consequently, shouldthe melting point of one batch of tallow be lower, it is necessary thatthe melting point be forced to the required temperature and this isaccomplished by the use of the same control for determining the meltingpoint of the composition.

For a normal pound lotof the compound, the end product is made asfollows: 65 pounds of tallow is introduced into a suitable receptacleand melted at the, lowest possible temperature, the temperature, ofcourse, depending upon the origin of the particular raw material used.After the tallow has been melted, 29 pounds of paraflin is carefullyadded and the tallow and parafiin are agitated or stirred by eithermanual or mechanical means, the temperature being carefully controlledbecause of the highly inflammable nature of the ingredients.

6 pounds of beeswax is then introduced into a separate receptacle orcontainer and is subjected to heat, and upon the beeswax being melted,1.3 ounces of citric acid is added thereto. A similar amount of oxalicacid and potassium citrate is then added to the molten beeswax.

The latter substance is then introduced into the molten tallow andparafiin and the whole is continuously stirred or agitated. 6.6 ouncesof urea are now added, after which a suflicient amount of Vienna Red isintroduced to provide the particular color desired. The composition isthen cast into the desired shape and can be packaged in any suitabletype of container.

As hereinabove mentioned, the melting point of the composition can beeffectively controlled and this is accomplished by the quantity of ureaemployed. By adding a greater amount of urea, a higher melting point isachieved, and by reducing the amount, a lower melting point results. Theparaffin functions as a carrier to prevent separation, and the beeswaxserves as a stiffening agent for the composition.

It is believed that the citric acid, oxalic acid and potassium citratefunction to make the compound substantially odorless which, of course,materially increases the desirability of the composition in theindustry. Furthermore, these particular ingredients also appear to aidin decreasing the greasiness of the composition which will eliminate agrease film being left upon the hands by handling the composition.

It will be appreciated, therefore, that the composition of the presentinvention is capable of many different uses in metal working processeswhich will be apparent to one skilled in the art. By virtue of thecontrol agent, the proper melting point of the product for theparticular operation being performed can be regulated within finelimits. This is highly important because of the various factors to beconsidered insofar as the type of abrading material, the metal beingspun, the nature of the cutting tool, etc. are concerned. The finalproduct may be easily and cheaply manufactured and does not deteriorateover extended storage periods.

The notation control material has reference to a material which controlsthe melting point of the composition.
